Hi Aleksandar,
> Add a subset of the functionality required for GDB.
Building the binutils configured as --enable-targets=all --enable-64-bit-bfd
I get a build failure:
/bin/ld: ../bfd/.libs/libbfd.a(elfxx-nanomips.o): in function `_bfd_elf_mips_mach':
bfd/elfxx-nanomips.c:227: multiple definition of `_bfd_elf_mips_mach';../bfd/.libs/libbfd.a(elfxx-mips.o):
bfd/elfxx-mips.c:6918: first defined here
Then there are the problems building readelf:
binutils/readelf.c: In function 'get_machine_name':
binutils/readelf.c:2962:5: error: duplicate case value
2962 | case EM_IMG1: return "Imagination Technologies";

Please could you check and fix these issues ?
Cheers

Hello Nick,
Thank you for your time.
I fixed the errors and sent the revision v4.

All the best,
Aleksandar
